Abstract

A CMOS imager system (300,400) including an active pixel sensor (302) having access supply which provides distributed feedback, a column buffer (304) (having gain and FPN suppression), and an A/D converter (312) co-located with the sensor such that the effective transmission path between the column buffer (or optional analog PGA) and the A/D converter (312) acts as a resistor, rather than a reactance. The system may further include both an analog gain amplifier stage and a digital programmable amplifier stage (314,402).
